The Kumhos have got me better fuel economy than the Conti WinterContact at 56.8 mpg versus 54.5 mpg. They perform well on snow-covered roads and I have no concerns about them. (I tend to drive with caution according to conditions, however) They are still a bit noisy, but after around 2,000 miles, tread wear is quite minimal and I have yet to notice any. Of course, summer tyres will be put on when the season changes.
